Going Green
Human beings and animals have been facing many environmental issues, such as climate change, air pollution, emission of greenhouse gases, deforestation and many other serious problems. As a consequence, people's health problems involving the respiratory system and kidneys are getting worse and worse, animals' habitats are destroyed, and many species are becoming extinct and endangered at an alarming rate. Hence, we need to take action by doing the following activities.
Recycling
It is advised that rubbish should be categorised into different types with three different colours: the blue, the green and the black bin. The first bin is for paper, plastic, and glass. The second bin or the compost bin is for organic waste, such as banana skins, coffee grounds or apple cores. The last one is for miscellaneous items which cannot be taken to a recycling centre.
Saving forests
First and foremost, people's awareness of conserving animals' habitats should be raised by frequent campaigns on local and global scales. Besides planting more trees, people can use fewer wood products, such as paper napkins, paper towels or books. Instead, these items can be replaced by cloth napkins, cloth towels, e-books and recycled-paper books. For those who go camping in the forests, they must extinguish their campfires before leaving these places.
Saving energy
One of the ways to save energy is to use renewable energy like solar and wind energy which is not used up as fossil fuels like coal, natural gases and oil. For a household, a solar panel can generate enough electricity for heating water, lights and other necessary appliances. Along with this, using energy-efficient lights is a good solution for saving not only the environment but also your wallet
